Answer: filename and extension.
Explanation:
Suppose we have %~nxa, where we have two modifiers n and x, and a single variable a.
So, the n modifier after the tilde forces the index variable to expand only to the filename(by the n modifier) and the extension(by the x modifier).
It produces the filename and extension instead of the full path.
Answer:
Option d) B is 1.33 times faster than A
Given:
Clock time, 

No. of cycles per instructions, 

Solution:
Let I be the no. of instructions for the program.
CPU clock cycle,
= 2.0 I
CPU clock cycle,
= 1.0 I
Now,
CPU time for each can be calculated as:
CPU time, T = 


Thus B is faster than A
Now,


Performance of B is 1.33 times that of A
